The main challenge in manufacturing a curved tortoise back watch buckle is polishing thickness inconsistency on the arched surface. Many manufacturers struggle with uneven material removal, which leads to unstable finishing quality. After electroplating, this often causes color difference and haze spots, reducing the overall luxury appearance and consistency.

Our solution is a fully controlled precision process: we use custom CNC pre-form compensation, high-precision uniform polishing fixtures, and multi-stage finishing to ensure even surface thickness. Combined with stable electroplating process control and strict surface activation before plating, we effectively eliminate color variation and ensure a clean, mirror-like finish on every buckle.
